The reference types wasm proposal dropped all subtyping. Subsequently,
the 'anyref' type was renamed to externref.
This changes all references of the *type* anyref to externref.
Additionally, the flag that permits this extension is renamed to
"reftypes" to mirror the proposal name.

the second is the initial value:
new WebAssembly.Global({type: i32}, 42);
If the initial value argument is omitted, the value is set to 0.

This change implements the WebAssembly.Global object and constructor,
but none of the accessors or functions.
There is a new flag to enable this: --experimental-wasm-mut-global.
